FISH BREEDING PONDS. 
the first salmon trout which have been introduced into 
the colony. They differ from the salmon in that although 
they visit the sea when available, they will live and 
breed without doing so ; thus a yearly supply of young 
fish may be obtained. For sport and the table the 
salmon trout are by many deemed equal to the true 
salmon. Like the salmon, the young change from the 
par state to the smolt, and with the exception of those 
retained for breeding purposes, will be allowed to leave 
the pond when they arrive at that stage. They will 
gain access to the sea by the Deep Creek and Salt- 
water River ; and if, as is believed, they succeed and 
return to fresh water, probably the result will be 
known sooner than has been the case in Tasmania, for 
not only are the waters through which they must pass 
narrower, but the fish can hardly pass up the fish 
ladders which they must ascend without being seen. 
No time should now be lost in obtaining an Act of 
Parliament, similar to the Trout Act in Tasmania, 
embodying in it such clauses of the Salmon Act there 
as will be required for the protection of the salmon 
trout. 
The next place must be given to the English perch : 
The history of their original introduction is not 
generally known, and may be interesting, as the result 
is almost incredible. During four successive years 
prior to 1861 attempts were made to introduce the 
perch to Tasmania from England, but it was not until 
December of that year that a fifth attempt succeeded, 
when— as in prior attempts— at Mr. Morton Allport’s 
request and sole expense, the writer brought out under 
his personal charge and landed live fish, which were 
placed in ponds expressly built for them by Mr. Allport.
